Electrophoretic coating for auto parts industry
Product Introduction
HL-1607LB/HLS-1701A Black Cationic Epoxy Electrocoat for auto is a
new generation electrophoretic coating researched and developed by
HLS Paint (Shanghai) Co., Ltd. It represents modern technology of
cathodic electrophoretic coating that is environment-friendly with
high property and low cost. Such coating does not contain heavy
metal like lead, tin, cadmium and mercury etc. It is a
two-component, water-dispersed resin,meanwhile, it took in features
of previous products, and can adapt galvanized steel sheet
perfectly, almost can be applied to foundation coating of all
metal, such as: cold and hot rolled steel sheet, galvanized steel
sheet, aluminum products and stainless steel sheet etc.
This product features shown below:
The bath has strong anti-shrink age andanti-pollutionability.
Coating fullness of good,better sub strate hiding.
Strong anti-corrosion properties, good salt spray resistance
workpiece edge.
The appearance of the coating is flat, delicate, smooth, uniform
high gloss.
